Mr Hancock refused to give any early indication of what extra measures businesses might be told to follow, telling Sky News' Kay Burley@Breakfast: "There's already rules in place that we've brought in to deal with the crisis."

He also addressed fears about the privacy of an app residents on the Isle of Wight are being urged to download as part of a trial of the South Korea-style "test, trace and trace" programme that means someone is alerted if their phone registers they have been in close proximity with an infected person.

"The liberties as a nation we're having to give up in order to tackle this virus are already enormous," Mr Hancock admitted.

Sir Keir said there should be "consensus" about how to lift the lockdown but called for the "core principles" of how the UK will operate in the next few months to be laid out.

"People are very worried about going back to work - understandably, they want to know what they are going back to is safe and that means there are rules in place," he told Sky News.
